We present results from microwave background observations at the Owens Valley Radio Observatory .
These observations , at 14.5 and 32 GHz , are designed to detect intrinsic anisotropy on scales of 7 ^ { \prime } -22 ^ { \prime } .
After point source removal , we detect significant emission with temperature spectral index \beta \simeq - 2 towards the North Celestial Pole ( NCP ) .
Comparison of our data with the IRAS 100 \mu m map of the same fields reveals a strong correlation between this emission and the infrared dust emission .
From the lack of detectable H \alpha emission , we conclude that the signals are consistent either with flat-spectrum synchrotron radiation , or with free-free emission from T _ { e } \lower 2.15 pt \hbox { $ \buildrel > \over { \sim } $ } 10 ^ { 6 } ~ { } K gas , probably associated with a large HI feature known as the NCP Loop .
Assuming \beta = -2.2 , our data indicate a conversion { T _ { \it f } / I _ { 100 \mu { m } } } = 7.5 \times 10 ^ { -2 } ~ { } \nu _ { GHz } ^ { -2.2 } K/ ( MJy/sr ) .

The detection of such a component suggests that we should be cautious in any assumptions made regarding foregrounds when designing experiments to map the microwave background radiation .
